Steve,
Thanks for the feedback, as always :D
I'm a bit tired, so right now I am only going to go into the one question for which I have a clear answer in mind, and that's the one about RUN!
You're right, RUN! is problematic as written. I need to write more text. Here's what I've been doing, and it works pretty well:
If the person making the move (referred to from here on as the RUNner) chooses the option to pick someone to go with them, unless there's some reason not to, that person is GUARANTEED safety. They do NOT have to tempt fate.
If the selected person is a PC, and they choose to go along with the RUNner, they just go with them and don't tempt fate. If they choose to do anything else, such as make a move of their own or just not go, they don't get this guarantee. I generally let the RUNner choose again in those instances, depending on situation. The same goes if the selected person is an NPC, only that they cannot make a move themselves, naturally. If there's some reason for them not to go (they're instrumental in another PC's move, or they don't want to go along, as the fiction demands), then they can't be the person guaranteed safety.
Anyone else other than the selected person *can* go along with the RUNner. They are just not guaranteed safety. If the RUNner chooses one pc, and a second one wants to go with them, then the second one rolls to help the RUNner. if they get a partial hit, they can wind up wherever the RUNner does, but they generally tempt fate, as they exposed themselves do danger. On a full hit, they don't have to tempt fate either, and the RUNner gets a +1. I let the selected person roll to help too if they want. Other options are reading the situation or a person, or opening their mind; all things they can do while legging it.
Other NPCs (beyond the first chosen person) obviously make the help move, or any other. What I do in that instance is look at what the RUNner rolled. if it's high, I let most of them make it ok. If it's a partial hit, ANYONE beyond the first person selected to be safe is in the crosshairs.
A good way to think about it is the person the RUNner selects is the one they take in hand and shout RUN! to. :) I am going to write expanded text on each move for variations like this. Also, I'm going to answer more of your questions, just after I sleep a bit.
